I've done a couple of AR receivers, two pistols, and some plastic stocks, but no revolvers. All turned out fine and are durable. The key is to thoroughly clean then degrease with alcohol, set the can of AG II in a pan of warm water so it sprays easier, use multiple *THIN* coats a few minutes apart, then set aside for at least a week at room temp to cure. Two weeks is better. Works for me.
FWIW
YMMV
